Cerebral Surface Of The Greater Wing, Superior View

Description

Sphenoid bone anatomy centers on the greater wing’s cerebral (endocranial) surface, a broad concavity forming the anterior portion of the middle cranial fossa. From a superior viewpoint, the smooth, gently curved plate lies lateral to the sphenoid body and medial to the squamous temporal region, creating the bony bed that underlies the temporal lobe. The sphenoid ridge marks the transition toward the anterior cranial fossa superiorly, while the anterolateral margin approaches the frontoparietal region near the pterion. Openings associated with the middle cranial fossa, including the foramina rotundum, ovale, and spinosum, are encountered on this internal surface near the root of the wing. Short and broad. Skull base work lives or dies on this terrain: the foramina define corridors for V2 (foramen rotundum), V3 (foramen ovale), and the middle meningeal artery (foramen spinosum), and their close proximity to the temporal lobe and cavernous sinus region drives both operative planning and radiologic localization. Grooves on the cerebral surface can align with the course of the middle meningeal vessels, tying the anatomy to epidural hematoma patterns after trauma at the lateral skull. A superior, endocranial perspective makes the fossa contours and foraminal relationships easier to teach than an external view, where the same landmarks are split across multiple surfaces. Use this illustration for neuroanatomy and head and neck teaching when introducing the middle cranial fossa boundaries, pterion-level vascular risk, and skull base foramina in a single frame. It also fits neurosurgical and ENT publishing needs for middle fossa approach orientation and for labeling V2, V3, and middle meningeal artery entry points without distraction from facial or orbital structures.
